CFD_Now is on a distinguished road
Hi All,

I'm simulating hydrogen+air catalytic reaction using Fluent (and Chemkin). I put the correct mechanism file and I'm sure about that. When the simulation is done, the mass fraction of H2 decreases because it's being combusted. But O2 mass fraction (and mole fraction) goes up!! It should be decreased but it's going up!! I'm using ideal gas model.

Please tell me if you have any idea about it!

Thanks
